Syntax

value = guid()

Arguments

value: text

Meaning

The GUID function generates a 16 byte (128 bit) globally unique identifier, that could be used as a persistent ID for a record for example. A GUID is a pseudo random number which is supposed to be unique in the world. Although not a 100% guaranteed unique, the total number of unique keys is so large that the odds of a certain GUID being created twice is very, very small. An example of a GUID would be: 963d5dab-2d6e-4bd8-9f71-6245ba795a50
